Hello Everyone,
The folks at http://www.hamtestonline.com have just put in a
configuration option to exclude the questions with graphics for blind
users. They were very responsive to my request for this feature.
This is a subscription based learning system that provides tutoring and
practice tests. There is a free trial for those who would like to check
it out. So far, it looks pretty good and is completely accessible. I
have no relationship with these guys financial or otherwise.
